Mounted plow with active moldboard

FIELD: agricultural engineering, in particular, heavy soil tillage technique.

SUBSTANCE: plow has frame, casing with shortened moldboard and rotating moldboard mounted above shortened moldboard and provided with knives fused thereto by means of hard alloy. Knives are made curved in their upper parts along parabola, with apex oriented downward. Lower parts of knives, not in the excess of one third of knife height, are curved along hyperbola, with apex oriented upward. For overcoming of loads connected with operation on heavy soil and for uniform rotation, rotating moldboard is equipped with impeller.

The invention relates to agricultural machines, namely, tillage tools, and can be used when processing heavy soils.

Known the plow with the active blade, in which the active blade is made in the form of a vertical rotor with loosening elements [1].

A disadvantage of the known device is that the working elements of the rotor are not cut, and beat the reservoir, MultiRAE the soil and leaving an abundance of weeds, not closing up.

The closest to the technical nature of the claimed device is a plow mounted with the active stockpile, including the case with a short blade and mounted behind the rotating rotor blades [2]. Knives curved shape of the blade at the section at the end of the plow blade.

The disadvantage of this plow is poor incorporation of crop residues and poor mixing of the topsoil and the underlying infertile soil layers.

The objective of the invention is to improve the quality of soil, in particular the full incorporation of plant residues.

This object is achieved in that the plow with the active stockpile, including the case with a short blade and mounted behind the rotating blade knives, weld hard alloy with a vertical axis of rotation, according to the invention the knives in the upper part bent by the parabola, the vertex downward, and in the lower part, not exceeding one-third the height of the knife along the hyperbola, with the apex directed upwards. In addition, the plow is equipped with a flywheel mounted on the shaft in the upper part of the active blade.

The new device is the shape of knives, bent on the parabola at the top and on the hyperbola at the bottom, and the upper part of the active blade on the shaft of the flywheel.

Thus, the invention conforms to the criterion "novelty".

The invention meets the criterion of "inventive step", as can be achieved the result that satisfy the existing demand, namely improving the quality of soil.

The invention is industrially applicable", because it can be used in agriculture.

The invention is illustrated by the drawing, which shows schematically the working body of the plow with the active blade, side view.

Plow with active blade consists of a frame 1, Lemeshko-dump body with shortened blade 2, plowshares 3, active blade 4. Active blade 4 is a shaft 5 on which there are four diaconate knife 6, curved in the upper part of the parabola, and at the bottom, not exceeding one-third the height of the knife by the hyperbole.

To better cope with the pressures associated with work on heavy state of soils in construction and is effective blade 4 also includes a flywheel 7, that significantly reduces inertial forces and contributes to a more uniform active rotation of the blade 4. The flywheel 7 is made in the form of a metal of a truncated cone and is mounted on the shaft in the upper part of the active blade 4.

The plow works as follows.

When moving the unit plough body with shortened blade 2 cuts the reservoir and delivers it to the rotating shaft from the PTO active blade 4. The lower barren soil, cut plowshare 3, getting on the lower part of the knife 6, bent on the hyperbola, with the apex directed upwards, crumble and rotates 180°. The upper fertile layer of soil with stubble, cut off the top part of the knife 6, the curve a parabola, with the apex pointing down, crushed and rotates 180°, closing up all residues. This fertile top and bottom marginal layers are not mixed. The fertile layer of the soil always remains at the top, thereby increasing the yield of agricultural crops.

After the passage of the claimed device, the surface field is obtained aligned, without ridges, furrows and air pockets. All topsoil at a depth of plowing 25 cm listens to 43 cm with the incorporation of all crop residues to a depth of 10...12 see

SUBSTANCE: method provides for disking and ploughing. Disking is performed simultaneously with ploughing using flat disks and is realised by cutting turf layer into strip parallel to plough movement. Strip width is not equal. Widest strips are cut at the longest distance from landward edge of plough. Width of the most distant strip from landward edge is from half to two thirds of grip width. Each next strip has the same ratio. Plough includes frame, housing and disk knives. Disk knives are installed in front of each plough housing so that the farthest from landward edge disk knife shares the width of grip in ratio from half to one thirds of the given edge. Next knives share the remaining width between landward edge and neighboring knife in the same ratio. Rotational axes of adjacent disk knives are shifted with regard to each other in plough movement direction at the value, which less knife disk diameter.

EFFECT: reduction of power costs, increase of productivity and improvement of matted soil treatment quality.
